Intel just demonstrated 14nm Broadwell ULT (Y-series) silicon, normalized for performance against 22nm Haswell ULT (Y-series) silicon running a multithreaded Cinebench test. Intel was monitoring SoC power during the benchmark and demonstrated a ~30% reduction in power, at the same performance level.

The other reveal? Broadwell ULT, albeit still a two-die, single chip MCM, is physically smaller than Haswell ULT. A physical size reduction is necessary to get Broadwell into fanless tablet designs that can have competitive battery capacities to ARM based designs. 

The first Broadwell silicon is supposed to ship to customers by the end of this year, and in systems next year.

    true, but the choice will be there for same performance, 30% less power, 10% more performance, 10% less power, 15% more performance, same power.

    Just making up numbers here, take the 35W TDP Haswell (4765T). Broadwell equivalent would be 24.5W TDP for 4 cores, or perhaps closer to 35W TDP with 6 cores.

    I'd like to see what they'll do with the integrated GPU on 14nm. Should be able to fit a lot more EUs in.

    There's not enough main memory bandwidth to feed even Haswells GT3 properly, without Crystal Well.

    For the eDRAM version, I meant.

    That's what I'm waiting for.... a Surface Pro 3.

    Seems like we hear this every year... "This is the one that's really going to get us into mobile!" They must know that Apple is just itching to get their own chips into their MacBooks.

    Well, if anything, that might be interesting. Another CPU performance war, between Intel and Apple? Hrm......

    What do you mean like MacBook Air? MacBook Air all come with Intel processors.
